Founded in 2022 by chemical engineer Marissa Beatty, New York City-based Turnover Labs builds durable electrolysis systems that convert industrial waste CO2 into chemical building blocks. Its technology is designed to install within existing chemical-plant operations, giving manufacturers a way to reuse impure emissions rather than rely solely on petroleum feedstocks. The early-stage company is developing its platform from laboratory research pioneered at Columbia University toward industrial-scale deployment.
Dimensional EnergyFounded in Ithaca in 2016, Dimensional Energy licenses catalyst and process technology that turns captured carbon and other waste feedstocks into low-carbon fuels and chemical products. Its DEFT Fischer–Tropsch and reverse water-gas shift technologies are backed by operating data from a Tucson pilot plant and an industrial CO₂ demonstration at a British Columbia cement plant, with support spanning project development through operations. The company also has four issued patents and 12 pending.ITHACA, NY
CarbonQuestCarbonQuest is a cleantech company built around decarbonizing the built environment, with a leadership team whose experience includes energy software, smart-grid technology, and carbon capture. It began piloting its modular systems in 2021 at a Manhattan residential building, where the installation demonstrated that emissions reduction could fit into space equivalent to three parking spaces. Today, CarbonQuest works with commercial and industrial facilities to capture CO₂ at the source and turn it into a usable or removable material.
AlchemityAlchemity is developing modular, turnkey reactor systems that convert greenhouse gases and waste resources into cleaner fuels and chemicals. Based in College Park, Maryland, the company was founded by a team combining clean-energy deployment, Fortune 500 leadership, and three decades of energy research and product innovation. Its platform is designed for co-located production, with a roadmap from modular skids to larger integrated facilities.COLLEGE PARK, MD
Eco CarbonFounded in 2022, Eco Carbon is a Pennsylvania chemical company known for giving post-consumer expanded polystyrene waste a new purpose through a proprietary reprocessing method. It develops high-performance porous carbon materials for industrial applications such as purification and energy storage, turning a difficult plastic waste stream into useful specialty materials.BALA CYNWYD, PA
